Characterization of cellular immune response to chemically defined glycoconjugates from Leishmania mexicana subsp. amazonensis [PDF]

Infection and Immunity, 1986
Two defined glycoconjugates (GP-10/20 and FR II Phe) purified from Leishmania mexicana subsp. amazonensis were analyzed with respect to their ability to induce cellular responses in immunized and infected mice. Each glycoconjugate was recognized by specific immune cells, as assessed by the proliferative response of lymph node cells of immunized mice ...
